" The4 loom is illustrated in `l as coniprising a lay l.. havingv at the shipper' end of ythe loom a shuttle box 2 containing' a shuttle. 3 ,which carries a bobbiii'l havinga slot .3 in its barrel 'adjacent to the basethereofadapted to yreceive the end .of theffeelei" iiiion substantial exhaustion of theillinO',

the walls. of the shuttle box and shuttle be-A l i -ingprovided with fthe .usual aperturesli and .71 to pei'iiiit the feelery ltdenter and feelupon `the filling upon the bobbiii or filling carrier'.

The opposite endl of the loom is shown asr provided with a companion sli'iittle' liox Sg the usual batteriv or filling: feeder' being located above ythe saine so that bobbiiis may -lie transferred theretroiiito the actuated-inthe usual manner. The action'.

of the transfer-rer, is controlled through controller shaft'. llfwhich extends longitu-v of the-breast beam-1 2 and ispror "id cd with Van upstanding arm 13 pivotally connected a"`latch 1i which may 'be pro! vided with a. notch adapted to be engaged.

stand and is provided at its upper end with a rearward vextension '27. having 'a cylindrical 28`for the feeler 29. The feder-29 -is pivotally mounted upon the upperend of 'u lever 30 which is pivoted upon a stud 'provided at asuitable point intermediate its ends with a lateralprojection or ledge 31 toengage the end `of the transmitter arm to control the laction ol; the. mechanism for changing nthe operation ofthe loom. The lever 30 is provided with a rearwardly extended weighted arm 3 3 adapted normally.

to maintain the feeler inextended or feeling and with a preferably integral forwardly extendinetall 34 ada ted to be envguard by a mem to withdraw the feeler from feeling posltion m'hen the loom is stopped.

1 1 The transmitter, which is shown herein 37 projecting laterally .from a flange or lug 38 `extending upwardly from7 the .shipper standgand'is'pdapted :to cause the engageV ment of aconstantly vibrating member such a'sfa vdog upon'the end of the vibrating actuator`.arm,'f with the latch vof the controller. llarm. Thearms of the vtransmitter. may be i"curved,downv'vardly .beneath the .plane of the breast beam, and the arm which is ad.

v-jacent to the feeler may be provid'ed with a Weight 39 adapted to counterbalance the.y

weight of the longer arm 36. The end of the 5 .arm 3 5: is olset in sucha manner that it is normally positioned beneath the ledge 3l of. the'feeler' arm 30' 'so that when the feeler is" in :forwardly extended posit-ion the. arm' 35,.

A"ai V36 o'fthe transmitter. is offset,

a downward movement o saidarmf The upper end ofthe armdsirablyis provided 4with a horizontal vcylindrical extension Y43 which when the arm-36 is held in normal or raisedfpositionby the ledge '31 of the feeler lever is adapted to enga-ge apivoted dogll carried by the vibrating actu-l ator or weft hammer and rock the same into engagement with the latch of the controller* shaft .to `actuate the latter. The dog 44 is supported upon a stud 45 extending laterally from an extension 46.

which is secured to the upper end of the -latcrallyextending arm 15 .of the weft hammer or vibrating actuator, this extension being desirably secured thereto' by un adjustable slot and bolt connection. The dog 44 preferably imp rovided with an integral tail 47 engaged by a spring 48 resting upon a ledge 4 9 andat'laptcd normally to keep the dog in i a depressed position whereby upon' each forward movement of the vibrating actuator it will contact with the-extension 43 of the transmitter arm.

'In' the preferred form of the invention illustrated hereinthe latch 14 is cut away onA its under surface to. form a notch orr shoulder 50 adapted to be engaged bythe *dog il and isv desirably'provided at its end withy an upturned portion 51 adapted to c0- operate with a stud 52 carried by the upper end of the extension 4 6' to prevent displament of the latch 1l from operative position.

The spring 48 which controls the dog is -of sullicient strength to cause the end of the degli to depress the arm 36 of the v'transmitter lever upon'each forward movement of the vibrating' actuator raising the arm lwhen the latter is not restrained by the ledge 31 of the feeler lever.

.the feelel" 29 will b e engaged by the filling During the normal operation of the loom upon 'the Abobbin upon each'forward-movementv of the lay and will begforcedjl forward thereby removing the ledge31" from its normal position above the end of the arm` 35 4olfthe transmitter, thus lpermitting the same to tipped upwardly by. the .engagement of 'the end of the dog l-lwith the extension .43, ofthe transmitter-arm 36. Vhen how# everf the fillngjupon the bobbin becomes suilicientlyexha usted to I"expose y the 4recess or` slotin the. bobbin barrel, the'1 feelerA will enter Vthe rand* Ithe ledge 31y will not be removed fromit's normal position over -rcstraintfthe 4dog 444 will not be able to' depress the arm A36'of the transmitter u n .Contact with.. thej fextension 43' thereof, ut
